Answer:
Its the third one
Step-by-step explanation:
Plot all of the points onto the graph, and draw a line through all of the points. It most closely resembles the third one
The formula for the amount A in an account with principal P and interest rate r compounded annually for t years is
... A(t) = P(1+r)^t
You want to find A when P=400, r=0.05, and t=3. Substituting those values gives you
... A(3) = 400·(1 +0.05)³
The appropriate choice is
... A. A(3) = 400·(1 +0.05)³

Complete question is:
Nancy is checking to determine if the expressions x+4+x and 6+2x-2 are equivalent. When x=3 , she correctly finds that both expressions have a value of 10. When x = 5, she correctly evaluates the first expression to find that x + 4 + x = 14. What about the second expression?
Answer:
when x = 5; both expressions are equivalent and equal to 14
Step-by-step explanation:
We are told the expressions are:
(x + 4 + x) and (6 + 2x - 2).
We are also told that when x = 3,both expressions are equal and have a value of 10 each.
Now, when x = 5; we are told the expression (x + 4 + x) has a value of 14.
So when x = 5,let's find the value of the second expression by putting 5 for x in (6 + 2x - 2);
So, we have; 6 + 2(5) - 2 = 6 + 10 - 2 = 14
So when x = 5; both expressions are equivalent and equal to 14
